Choropleth Map


This here is a picture of a choropleth map because it not only using different color depictions but it also gives information within each area saying which state is which. Using certain indicators such as these is proof of a choropleth map. Another way to describe an choropleth map is by saying it is based on predefined areial units. You can observe from this picture the states that chose to vote for either George Bush or John Kerry in their election


Dot Distribution Map


A dot distribution map is used to show populations within a certain given area.

This picture of a dot distribution map shows the population of each state in both 1990 and 1996. The blue half of the dots are representing the 1990 population and the red half is representing the 1996 population. It is clear that the larger the dot the greater the population within that state as well. California, Texas, and Florida are showig the biggest dots and this corresponds well with the amount of people these states have. As well as with the smaller states such as Rhode Island, New Hampshire, and Vermont, their dots are smaller than everyone elses. http://hosting.soonet.ca/eliris/remotesensing/bl130lec7.html

Propaganda Map


This here is clearly a propaganda map! It is showing the world how Ronald Regan would choose to view it. With the USA obviously being the biggest and most powerful. With nothing good to say about the countries in the middle east, and making California the biggest country within the US. A propaganda map is basically a lying map. It shows what the cartographer chooses to show, with their opinions and their ideas. This is definitely not a factual map nor will it ever be.


Hypsometric Map


This picture here is showing a Hypsometric map of the Isera Mountains. This is a hypsometric map because it clearly shows the relief by the countrouring lines, shading and tinting. Also is also a hypsometric map because these maps usually use a shading from green through yellow to brown just as it is shown here within this map. The blue line is showing the outline of the Izera Dark-Sky Park. And with the white line representing the Czech-Polish border there are bound to be segregation issues within this park.


PLSS Map



A PLSS Map is that included in the Public Land Survey System. Within the US they use this asa a way of subdividing and describing land. Another name used by the US for PLSS are rectangular survey systems. This map makes it very clear to see the different numbered sections showing which land parts belong to which section. This PLSS map is nice because the cartographers made it easy to read as well as understand.

Cadastral Map

This is map shows distinct boundries and ownership between the land area therefore making it a cadastral map. A cadastral map like this one can sometimes provide a cartorgaphic record of official and sometimes private land surveys and subdivisions. http://www.dimensionicad.com/india/cad-parcel-mapping.html

Thematic Map


The color depictions given within this thematic map how the median ages in the year 2000 within each state. This is one of my favorite maps because they are very easy to read and also for a cartographers it is easy for your point to be made. This thematic map in perticualar is able to show census data in a graph formation. Even though you can only partially see it at the bottom of the map, Florida is the darkest green color indicating that we in 2000 had one of the highest populations on the east coast.
